angularjs - 为什么 Karma 显示范围错误？

Question

我正在 jasmine 中为 angularjs 编写测试用例，并使用 karma 作为测试运行器。之前，一切都运行良好，但突然出现 [RangeError: Wrong length!]。我什至不知道如何在它发生的地方调试它。请帮助..

这似乎是最新的 karma 版本 (0.13.16) 中的错误。检查这个问题:https://github.com/karma-runner/karma/issues/1768 .

如果您已更新到 karma@0.13.16 并且启用了 coverage 报告器，您将遇到此问题。

现在这个问题还没有解决，所以你可以降级到karma@0.13.15或者禁用coverage reporter。问题修复后，可能会发布新的补丁版本。
